You hop to the left stone, and you're suprised that the surface of it is covered with some sort of sticky ooze, which grips your foot, allowing you to gain a footing. From there it's just an easy hop and a skip, and you land on the little islet, the wet grass cold against your feet. The woman continues to hum and sing, and now that you're closer you take a second look. Her skin is bluish-gray, her midrft, her back, her shoulders and her hips are covered with smooth silvery scales. Her green hair the color of seaweed, which shares the pigment with the little hairs between her ass crack. There's this strange translucent webbing that connects her arms to the side of her chest and her legs together, most likely something that lets her swim better in the water.
Her ass is plump with a hint of red, the closest color to human skin on her entire body. It looks enticing, and she still hasn't noticed you. Perhaps you could sneak up slowly and ravage her backdoor.

Yeah, that's seems like a good idea. The more you think about it the more you want to do that. She just continues to hum, her hands playing with the grass.
